Voltage: 220V AC, 50Hz (same as Europe, different from US 110V)
Plug Types: Vietnam primarily uses Type A, C, and G outlets:
Many modern hotels feature universal outlets accepting multiple plug types. Older buildings may have only Type A or C.
Universal Travel Adapter: Recommended for flexibility across Vietnam and other Southeast Asian countries. Look for adapters with USB ports for charging multiple devices.
Voltage Converter: Only necessary for devices NOT dual-voltage (hair dryers, straighteners, some older electronics). Most accommodations provide hair dryers.
Power Bank: Essential for day trips and long exploration days. Hanoi has reliable electricity but charging points aren't always convenient.
Surge Protector: Optional but useful for protecting electronics from power fluctuations, which occasionally occur.
Most hotels (3-star and above) provide:
Buying Locally: If you forget adapters, electronics shops in Old Quarter sell them cheap (50,000-150,000 VND). Convenience stores and hotels may loan/rent adapters.
Power Outages: Rare in Hanoi's tourist areas but can occur during storms. Hotels typically have backup generators. Keep devices charged and carry flashlight/phone backup.
